Hop on a ferry or hire a boat and skipper to take you to gardens, pagodas, temples and islands. Alternatively, rent a bike and pedal the 7km Northwest Route, a flat path that connects many of the beauty spot’s most celebrated sights.

2. Kelimutu

Visitors get no fewer than three crater lakes to swoon over at Kelimutu, on the Indonesian island of Flores. Even better, they change colour every so often, from bottle green to electric blue, red, brown and black, as a result of chemical reactions triggered by volcanic activity.

Islanders believe Kelimutu (“boiling mountain”) is the final resting place of departed souls, and offerings are made to the spirits living in the lakes. Viewpoints are busy at sunrise and sunset, so consider a midmorning visit.

Be sure to watch your footing – a number of people have fallen or jumped into the toxic, acidic waters. In 1995, a Dutch tourist fell in but, despite a week-long search, his body was never recovered.

3. Lake Como

Casino Royale, Star Wars: Attack of the Clones and Ocean’s Twelve were all filmed on the Italian lake or at properties along its shores.

Meanwhile, the hoi polloi marvel at mountain vistas, picturesque port towns, parks and palaces from the public ferries that connect Lake Como’s villages. Surrounded on three sides by water, cute-as-a-button Bellagio, with its medieval alleyways, red-roofed buildings and manicured gardens, shouldn’t be missed.

4. Loch Ness

Loch Ness contains more fresh water than all the lakes in England and Wales combined – although this isn’t the Scottish loch’s principal claim to fame, of course.

Sightings of the Loch Ness Monster date back to the 6th century and continue today (a video captured “something large” in May 2022). Marine biologists remain sceptical (they’re not alone), but this does little to diminish interest in Nessie.

Tourists break their journey to the Scottish Highlands to scan the 37km-long (23-mile) body of inky water in the hope of spotting a creature variously described as “long necked”, “humpbacked”, “jet black” and “dinosaur like”.

Spoiler: they don’t spot it.

5. Lake Titicaca

Straddling the border between Peru and Bolivia, Lake Titicaca at 3,812 metres (12,500ft) altitude is the world’s highest lake navigable by large vessels.

Boats shuttle backpackers from the sleepy town of Copacabana to mystical Isla del Sol, where rustic homestays nestle amid terraces of potatoes, beans and quinoa cultivated by bowler-hatted Bolivians.

Here on the high plains of the Andes, the sky is that deep, dark shade of blue you only usually see from a plane window, and the cool, crisp air is ideal for leisurely exercise.

The island’s cobblestone trails are littered with 15th century Inca ruins – some claim Isla del Sol, rather than Cusco, Peru, is the birthplace of the ancient civilisation.

6. Lake Victoria

Shared by Tanzania, Uganda and Kenya, Lake Victoria provides important trade and transport links, as well as food security and livelihoods for the 30 million people living on its shores.

Tourists busy themselves with fishing and birdwatching trips, and visits to villages dependent on cattle herding and coffee production.

The biodiversity of the world’s largest tropical lake is under threat, however, as overfishing and fertiliser run-off have led to an increase in surface algae. Introduced species such as Nile perch have decimated stocks of native fish and, as a result, water hyacinth grows unchecked, clogging the lake.

7. Dal Lake

The pride of Kashmir, Dal Lake is both calming and frenetic. The best place to stay is aboard a houseboat, complete with hand-carved cedarwood flourishes and British Raj-influenced interiors.

Opt for a relaxing voyage far from the commotion and clamour of nearby Srinagar city, or make a beeline for the bustle of the floating markets, where villagers sell flowers and vegetables from flat-bottomed shikara boats.

Instagrammers take advantage of the snow-capped mountain backdrop and “set-jetters” track down locations around the lake and across Kashmir that have featured in Bollywood films.

8. Moraine Lake

The glacier-fed turquoise waters also appeared as one of the Windows Vista Starter wallpapers and as the login screen of Windows 10.

On a still morning, the lake resembles a giant mirror – follow the 15-minute Rockpile Trail to a viewpoint overlooking the iconic body of water and the Valley of the Ten Peaks. Next, head along the 2.9km (1.8 mile) Lakeshore Trail, which offers equally jaw-dropping views, minus the crowds.

9. Lake Baikal

The world’s oldest and deepest lake holds about 20 per cent of Earth’s fresh water – roughly equivalent to all five of the North American Great Lakes combined.

Apart from walking and skating on the creaking glassy surface, wilderness adventurers sign up for husky dog sledding, cross-country skiing, ice fishing and jeep tours. There’s even a Lake Baikal Ice Marathon.

Most importantly, according to Siberian superstition, anyone who swims in the lake’s chilly waters is rewarded with an extra 20 years of life.
